bright yellow hue of the washed malms^ those bricks which are 

 formed of the yellow clay which has been exposed to repeated 

 washings, are thus accounted for. 



The septaria lie horizontally, and are disposed at unequal dis- 

 tances from each other in seemingly regular layers ; and, as has been 

 just observed of the stratum itself, they become of a paler colour, and 

 it may be added suffer decomposition, when placed so high in the 

 stratum as to be exposed to the action of percolating water. They 

 frequently include portions of wood pierced by the Teredines^ Nautili^ 

 and other shells ; and it is a fact that may be worthy of being attended 

 to, whilst inquiring into their formation, that the septa of calcareous 

 spar frequently intersect the substances enclosed in the septaria. 



This stratum is to be found not only wherever the preceding 

 deposition extends, but in other parts also where that has been 

 removed. The cliffs of this clay, at Shepey, extend about six miles 

 in length ; the more elevated parts, which are about ninety feet in 

 height, being about four miles in length, and declining gradually as 

 they terminate towards the east and west. 



The fossils of this stratum have been already carefully particula- 

 rised. A catalogue of those found at Shepey was added by Mr. 

 Jacobs to his Flanta Favershamienses ; and an account of several 

 of the fossil fruits found at Shepey was published by Dr. Parsons in 

 the fiftieth volume of the Philosophical Transactions. The fossils of 

 Hampshire have been scientifically described by Dr. Solander, in the 

 Fossilia Hantonensia of Mr. Brander, where the fossils themselves 

 are very exactly figured. 



It was not supposed, even after the publication of these accounts, 

 that the fossils of Shepey and those of Hampshire were of the same 

 stratum. Among the Plampshire fossils no mention is made of 

 crahs^ lobsters^ tortoises ^ nautili y nor of the h-eads or bodies oijishes
